Alex Neil has been sacked as the Canaries manager following a unanimous decision from the club's board.
Neil previously guided Norwich to the Premier League for the 2015/16 campaign and kept his job despite suffering relegation from the top flight the same season as he was viewed as the right man to get the Canaries promoted again.
But after a difficult season in charge at Carrow Road, where he was given support in December from the board despite demanding improvement after a poor run, it appears they have now run out of patience.
It looked as though that improvement had come late in January and into February as the Canaries won four out of five games, including a 5-1 thrashing at Nottingham Forest. But it didn't last and without a win in their last five games the board believe it is time for a restructure at the club.
In a statement released on the club's website, it read: "The Board has taken the tough but unanimous decision, believing it is in the best interests of the Club for a new manager to be in place through a crucial summer transfer window and into next season.
"The Directors would like to place on record their sincere gratitude to Alex for all of his hard work and for the fantastic achievement of guiding us to the Premier League in 2015, via a memorable play-off final success against Middlesbrough at Wembley.
"Through tough seasons last year in the Premier League and this year in the Championship, Alex has always given his all to the Club and we wish him every success in his future career.
"As has been widely reported the Board has been conducting a thorough review of the structure of the Club. An announcement about the new structure will be made next week."
First team coach Alan Irvine will be in charge for tomorrow's game against Blackburn Rovers while former Birmingham City manager Gary Rowett is the bookies' early favourite to land the role and is odds-on with SkyBet.
